Devonian were gas chromatographically analysed for low molecular weight aromatic hydrocarbons. Aromatic hydrocarbons range from 0.5 to 45.6 per cent with benzene, toluene and the xylenes averaging 80 per cent of the aromatic content. Trimethylbenzenes (of which 1,2,4-trimethylbenzene is the most ...
For a pulse of 1.18 cm3 of trimethylbenzene isomers and 40 g of molecular sieves 13X, the effects of pressure, temperature, and flow rate on separation effectiveness were examined. The results indicated that the most appropriate operating conditions for obtaining a higher recovery of each isomer ...

Wet weight per plant was 1.10 g on average. Identifications based on retention indices and GC-MS: (1) oxalic acid, allyl hexyl ester; (2) bicyclo[3.1.0]hex-2-ene, 2-methyl-5-(1-methylethyl)-; (3) benzene, 1,2,3-trimethyl-; (4) 6-methyl heptanoate; (5) butyl pyruvate; (...
luminescence spectroscopy to understand the detailed extraction and complexation behavior of europium(III) using a renowned phosphonium based functionalized ionic liquid, trihexyltetradecylphoshonium bis(2,4,4-trimethylpentyl)phosphinate ([P66614][C16H34PO2]) dissolved in 1,3-diisopropyl benzene (DIPB)...
The molecule 1,3,5-tris(imidazol-1-ylmethyl)-2,4,6-trimethylbenzene (titmb) crystallizes as a monohydrate in the monoclinic space group C2/c with a = 20.888(4), b = 13.220(2), c = 14.385(2) Å, β = 90.36(1)°. Two of three imidazole groups are on one side of the central...
b The PXRD patterns of ideal and defective UiO-66. c The chemical structures of 31P probe molecules used in this work. “dU” represents defective UiO-66, “iU” represents ideal UiO-66, and “sim.” corresponds to the PXRD simulation result. TMP: trimethylphosphine, TMPO: trimethyl...
The present invention relates to an ultrahigh-molecular-weight ethylene copolymer powder having an intrinsic viscosity (η) of 10 dl/g to 34 dl/g, obtainable by copolymerizing ethylene and at least one olefin selected from the group consisting of α-olefins having 3 to 20 carbon atoms, cyclic...
